石墨炉法测定化探样品中银的试验

Determination of silver in Geochemical Samples by graphite furnace method

本文研究了用石墨炉原子吸收光度计测定化探样品中银的方法。进行了样品的溶样试验、基体改进剂用量试验和仪器加热程序的确定试验,确定了化探样品的溶样方法和仪器工作条件。实验对5个国家一级标准样品进行了定值试验,均取得满意的结果。该方法能够满足化探样品中银的检测要求。

This paper studied the spectrophotometric determination of laboratory test method for silver in geochemical samples by graphite furnace atomic absorption spectrometry. The sample solution test,the base improver dosage test and the determination test of the instrument heating procedure were carried out,and the solution sampling method and working conditions of the geochemical sample were determined. The five experimental results show that the test results are satisfactory.The method cauld meet the requirements of detection of geochemical samples.
